Question

Write a PYTHON program for the following:

A dictionary courses lists summer school classes a student is taking, along with information about the classes. For example,

courses = { "CS 101" :

{ "full_name" : "Intro to CS with Python", "instructors" : [ "Sally", "Johnson" ],

"tas" : ["Bob", "Joe",..., "Elroy"], "num_homeworks" : 6, "num_exams" : 2 },

"SPAN-SAA" : { "name" : "Beginning Spanish I", ... },

... }

Write a loop that computes the total number of homeworks that the student has in all of their classes. Bonus: write this in one line using the function sum and a list comprehension.

RAW CODE:

courses = { 
"CS 101"        :       { "full_name" : "Intro to CS with Python", "instructors" : [ "Sally", "Johnson" ],"tas" : ["Bob", "Joe",..., "Elroy"], "num_homeworks" : 6, "num_exams" : 2 },
"SPAN-SAA"      :       { "full_name" : "Biginning Spanish I", "instructors" : [ "Sally", "Johnson" ],"tas" : ["Bob", "Joe",..., "Elroy"], "num_homeworks" : 4, "num_exams" : 2 }
}

print(sum(dic["num_homeworks"] for dic in courses.values())) # nested command
# first dic will iterate to each value in courses dictionary
# than calculate sum(dic["num_homeworks"]) and print the result
